Transducers designed for the measurement of generator field currents (used with a shunt). The input is designed for 50mV or 75mV shunts and has an isolation rating of 3500 VDC. Standard output is either ±10VDC (model FCT-01-10V) or 4-20 mA (model FCT-01-420m). Housed in a fiberglass box with watertight fittings for cable entry and exit.
